Some creep creeping on a 15 year old

Don’t really know why I feel the need to post this story but I do. Last summer I was in a casino with my cousins and we were heading from the pool to our room. Now me, being the smart girl that I am, brought a towel with me to cover up my body that only has a bathing suit. My cousin however, felt the immediate discomfort when we walked into the casino from the hundreds of grown men that are there and asked for my towel. I of course gave it to her and was now walking through a casino with only a bathing suit. My cousin gave me her phone and I kind of held her phone to like cover my hooha cause you know you don’t want anyone looking there. I was focusing so hard on not making eye contact with anyone and just kept my eyes to the ground. All of a sudden, I hear my cousins calling someone a pervert and cussing them out. They tell me that someone was literally staring straight at where my hooha is and I felt like crying. I beat myself up over this for the next few months and felt like a total piece of trash. I will now always keep a towel with me to cover myself up and hope that other girls will do the same to keep themselves safe. I’m pretty much over it now but I know that if something like this were to happen again, I could never forgive myself.
